AMAT 0190-07908 four-channel DeviceNet Interface Card
AMAT 0190-07908 is a high-density, four-channel DeviceNet Interface Card specifically engineered for Applied Materials semiconductor manufacturing equipment.
Utilizing the 3U CompactPCI (cPCI) form factor and manufactured by SST (a Molex company, model SST-DNP-CPCI-3U-4-NC),
this card serves as a communication bridge between the tool’s central controller and its distributed field devices, such as Mass Flow Controllers (MFCs), pressure transducers, and heater jackets.

0190-08680: 2-Channel DeviceNet cPCI Card.
0190-07906: MESA Power Supply Card (often used in the same backplane).
0190-07910: Falcon PC-MIP 8-Serial Card.
Application Cases
The 0190-07908 is a staple in the control towers of advanced wafer processing platforms:
Chamber Subsystem Control: Managing DeviceNet-based gas boxes and vacuum pumps on Centura and Endura platforms.
Multi-Chamber Mainframes: Simultaneously coordinating process recipes across up to four chambers on a Producer mainframe.
Retrofit Projects: Replacing legacy communication cards during electronics upgrades to improve tool uptime and signal reliability.
Product Advantages and Features
Quad-Channel Density: Integrates four full DeviceNet scanners into a single 3U slot, maximizing rack space for other logic modules.
Electrical Isolation: Each channel is electrically isolated, ensuring that a short circuit or noise on one gas line does not propagate to the other three channels or the host CPU.
Industrial Reliability: Built to SST’s rigorous standards for high-vibration and high-EMC (Electromagnetic Compatibility) environments typical of a cleanroom.
Real-time Diagnostics: Features front-panel LEDs for rapid troubleshooting of network health, communication status, and baud rate mismatches.
Other Models in the Same Series
The 0190 Series contains the specialized cPCI and VME modules for AMAT:
0190-07907: 3U x 12HP Power Supply Backplane.
0190-07909: PC-MIP CRT & Video Graphic Controller Card.
0190-07911: 6-Slot 24HP cPCI Backplane.
Installation and Maintenance
Installation: Align the module with the guide rails in the 3U sub-rack. Use the injector/ejector handles to seat the 160-pin connector into the backplane. Secure the captive screws to ensure a solid electrical ground.
ESD Safety: This card contains high-density CMOS logic. Always use a grounded ESD wrist strap when handling the board or adjusting the cable connections.
Maintenance: Ensure the front-panel connectors are free of tension. Cable strain is the most common cause of intermittent DeviceNet communication errors. Periodically verify that the 24V DC network power (from the trunk line) is stable.
Unique Product Description
The AMAT 0190-07908 (SST-DNP-CPCI-3U-4-NC) is the essential “communication hub” for Applied Materials tools.
By consolidating four independent DeviceNet ports onto a compact 3U card, it allows complex semiconductor platforms to orchestrate hundreds of sensors and actuators with millisecond precision.
In an environment where signal integrity translates directly to wafer yield, this card provides the robust, noise-resistant interface required for modern sub-10nm chip manufacturing.
